Solution
This problem can be solved using a simple program in Python. Here is a step-by-step guide on how to do it:
Step 1: First, we need to take an integer input from the user. We can use the input() function in Python for this purpose. Since input() function returns a string, we need to convert it into an integer using the int() function.
a = int(input())
Step 2: Next, we perform the unary operations on the variable 'a'. In Python, the unary operators ++ and -- do not exist. Instead, we can use the += and -= operators to increment and decrement the value of 'a' respectively. However, in this case, we don't need to increment or decrement 'a' because the operation ++a * --a in C++ or Java is equivalent to a * (a-1) in Python.
a = a * (a - 1)
Step 3: Finally, we
